CHICAGO -- The Cubs have been trying to find spots for Junior Lake to get the outfielder back on track, but he's continued to struggle at the plate.

Lake batted .273 in May, then hit .190 in June and .114 in July. Manager Rick Renteria has started the right-handed hitter against lefties, but the Cubs had not faced many until their two series against the Rockies, and Lake went 3-for-15 in six games.

"We tried to run him out there against the lefties, and we'll continue to see where we can get him some at-bats," Renteria said. "He hasn't had many over the last three or four days, but we'll continue to find ways.

"He's been working really hard on his mechanical approach, and when we can, we'll try to get him in there."

Last season, Lake batted .284 in 64 games with six home runs. This year, he's hitting .216 in 95 games with nine home runs and 101 strikeouts.
